Interested in seeing the play, and maybe the rest of Woolly Mammoth's season? Here's a tip: get on or sign up for foursquare (it's free!). Head on down to Woolly Mammoth (it's local!) and show that you've checked in on Foursquare. Just like that, you'll get a season "flex" pass for $99 (usually $300!). The flex pass gets you six tickets to use over the course of the season for any date or time - you just have to reserve with the box office 24 hours in advance. You'll get 10% off tickets for your friends too.
